Benefits of technology

The present invention provides an archwire with a variety of cross-sectional shapes and areas along its length. This allows for the creation of a customized archwire that can be easily determined based on the bracket bonding positions and the type of loop and hook. The invention also solves the issue of the hook obstructing further teeth retraction and prevents the archwire from being released from its slot. Overall, this results in improved dentistry procedures and more efficient treatment outcomes.

Problems solved by technology

In particular, since a lower end of the hook is fastened to the wire, there is a drawback in that a volume of the archwire is significantly increased.
In particular, the above drawback is remarkable in the case of lingual orthodontic treatment in which a space is limited.

Embodiment Construction

[0049]Hereinafter, preferred embodiments of the present invention will now be described in detail with reference to the attached drawings, in which like reference numbers denote corresponding parts throughout the drawings.

[0050]The terms “comprising” and “including” in the discussion directed to the present invention and the claims are used in an open-ended fashion and thus should be interrupted to mean “including”, but not limited thereto.

[0051]An orthodontic archwire with a varied cross section which is formed integrally with hooks according to the present invention has a cross section varied along a region, contrary to an orthodontic archwire according to the related art.

[0052]For example, a loop, a hook or a stop can be formed by reducing a cross-sectional area of an inter-bracket region or varying a cross section of a desired region.

[0053]In addition, the cross-sectional area can be varied by dividing the wire into an anterior region and a posterior region.

[0054]To this end, si...

Abstract

Disclosed is an archwire with a varied cross section which is formed integrally with a hook. The archwire includes a customized archwire body corresponding to a setup model of patient's teeth, and the hook which is formed integrally with the archwire body. The archwire body is formed in such a way that at least one region has a cross section different from that of other region.

Description

TECHNICAL FIELD[0001]The present invention relates to an orthodontic archwire. More particularly, the present invention relates to a customized archwire for loop or sliding technique.BACKGROUND ART[0002]In general, orthodontic therapy is to straighten crooked teeth by bonding brackets to the teeth and placing and ligating an archwire to slots of the brackets, wherein the teeth are corrected by retracting the teeth using a restoring force of the archwire or controlling torque of the archwire.[0003]A method for retracting six anterior teeth usually employs a loop technique or a sliding technique.[0004]The loop technique includes bending a portion of an archwire to form loops, ligating the archwire to brackets, and anchoring the hooks to the brackets by a ligating wire to produce a retraction force.[0005]FIG. 1 is a view illustrating a process of forming a loop according to the related art.[0006]Referring to FIG. 1, a loop 1′ is formed by bending a portion of a wire 1 using a tool. If ...
